Another Perspective
I know everyone’s tired of the Reece speculation, but here’s one more perspective on why they might be keeping it hush hush for now.
If a major storyline is Reece considering retirement, it’s just as valuable to the show to keep it a secret whether she stays or goes. So if she doesn’t retire but someone else (say, Kylie or Karley) does, that keeps all the big speculation around their shining star either way. I don’t think them not sharing, or having a promo photo of Reece, is indicative of anything besides her having a storyline.
IMO people are really jumping to conclusions and not thinking critically.
